Two coffees, one standard

Not sure which one?

The base is the same: ground speciality coffee, 100% Arabica from Brazil, roasted in Poland. They differ in what goes in beside it, and in the part of the day we made them for.

FAQ

Questions, answered.

Yes. The base is 100% speciality-grade Arabica from Brazil: balanced and creamy, with notes of nuts and chocolate. The extracts work quietly in the background and do not cover the coffee. The chaga makes the cup a little darker than the roast suggests.

In its form, and everything that follows from it. Instant coffee is a brewed coffee that has been evaporated, and it loses most of its aromatic compounds on the way. This is ground coffee, so the aroma is released when you brew it, in your kitchen.

An espresso machine, a filter machine, a dripper, a French press, a moka pot or an AeroPress. Anywhere you would normally brew ground coffee.

93–96 °C. Boiling water (100 °C) pulls bitterness out of the coffee, so wait a moment after the kettle clicks.

Yes, and many people do. Brazilian Arabica stands up well to milk and does not get lost in it.

Three things: ground Arabica coffee, chaga fruiting-body extract DER 10:1 (500 mg a cup) and ashwagandha root extract DER 4:1 (500 mg a cup). Nothing else: no sugar, no flavourings, no creamer, no fillers.

That the beans went through a standardised sensory assessment, called cupping, and scored at least 80 out of 100. Aroma, sweetness, acidity, body and the absence of defects are all marked. It is the highest quality grade of coffee.

That 10 kg of raw material makes 1 kg of extract, so the 500 mg of chaga in a cup is drawn from 5 g of the mushroom.

No — a cup carries 500 mg of extract, and a daily serving of our capsules carries 1,000 mg. This is coffee with an extract milled into it, not a supplement you drink.

100 mg, all of it from the coffee itself. That is the figure printed on the pack.

Yes, for mycotoxins, in an accredited laboratory (GBA Polska). Aflatoxins came back below the limit of measurement and ochratoxin A well under the EU limit for roasted coffee. The report is linked on this page.

In Poland, in small batches.

Yes. Everything in the bag is plant or mushroom.

We built this one for the second half of the day: after lunch, after work, after training, or on a slow weekend morning. If you want a coffee to start the day, look at the Lion’s Mane coffee.

It is a real coffee and it contains caffeine, so the same rules apply as for any coffee. If you are sensitive to caffeine, have this cup at least 6–8 hours before you go to sleep.

Thirty cups of 11 g, which is 330 g. At one cup a day, a pack lasts a month.

We recommend one. Do not exceed one serving a day, and do not have it at the same time as other sources of caffeine.

In its bag, sealed, at room temperature, somewhere dry and away from light. Keep out of reach of young children.

It is not for children or anyone under 18, or during pregnancy or breastfeeding, or for anyone sensitive to any of the ingredients. It contains caffeine. Chaga is naturally high in oxalates: if you have a history of kidney stones or reduced kidney function, speak to your doctor first. Ashwagandha is not recommended alongside thyroid medication or sedatives without medical advice.
